Walkthrough

The level starts as a closed-off arena set in a hellish environment. The player starts off in the middle of the action surrounded by a multitude of pillars topped with Arachnotrons . Strewn along the floor at the feet of the pillars are a rocket launcher , multiple rocket boxes, a few Stimpacks , and a blur artifact hovering over each of them that cannot be avoided; once the player grabs an item underneath, he will automatically pick up the sphere. This makes the battle against the Arachnotrons easier to deal with.

Once the player kills all the demons, a Megasphere will spawn in the center of the map. Collecting the Megasphere will trigger the sides of the arena to lower, exposing more rockets and a Cyberdemon.

Once the Cyberdemon is killed, the arena's walls lower and unleash an army of Mancubi coupled with even more rocket boxes. Once the Mancubi are defeated, the level ends and takes the player back to MAP01: Staging Area.
